Mouth-to-lung (MTL)

A tight draw held in the mouth before inhaling – the closest to a cigarette. Use 0.8 Ω and higher with nicotine salts at 20–35 mg.

Restricted direct-lung (RDL)

A looser draw inhaled straight into the lungs, with more vapour. Use 0.4–0.7 Ω pods and lower strengths – freebase 3–6 mg or a mild salt.

Direct-lung (DL)

Wide-open airflow and big clouds from pod mods and sub-ohm tanks at 0.15–0.3 Ω and 40 W+. Use freebase at 3–6 mg only – high-strength salts at these powers are harsh.

Quick rule

• Higher resistance (Ω) = tighter draw, less vapour, stronger throat hit.
• Lower resistance = looser draw, more vapour, use lower nicotine.
• Not sure? A 0.6–0.8 Ω pod with adjustable airflow covers both.
